ToaZZ whom it may concern:

Be it known that 1, Nine MILLER, a subject of the King of Sweden, and a resident of Portland, in the county of Multnomah and State of Oregon, have invented a certain new and useful Improvement in Door-Hangers, of which the following is a specification.

One of the principal objects of my invention is to provide an improved door hanger of the lever type,by means of which the door is hung, free of rollers, runners, or other devices, in such manner as to be capable of movement into opening and closing positions along a constant horizontal line, and with a minimum amount of exertion.

Another object of the invention resides in the provision of a door hanger of the class described, which is capable of such adjustment that the door will return automatically to closed from open position.

A further object'is to provide an improved door hanger of the nature set out, characterized by simplicity, durability,'and economy in manufacture and maintenance.

With'these and other objects in View, which will become apparent as the description proceeds, the invention resides in the construction, combination, and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which like characters of reference indicate like parts throughout the several figures, of which Figure 1 represents a side elevational view of a door hanger constructed according to my invention, showing the samein operation, the door to which the hanger is connected being shown in half open position;

.Fig. 2 represents a similar view, showing the hanger as adjustedfor effecting automatic closing movement of'the door;

Fig.3 represents a sectional view taken vertically through the hanger;

Fig.4 represents a'view in perspective of the hanger; V

Fig. 5 represents a side elevational view of the hanger, showing the arrangement when the hanger occurs alongside of the door, the door being indicated in open position;

1 Fig; 6 represents a view of the arrange ment when the hanger is placed alongside the door, the door in Fig. 6 being indicated in half closed position.

Referring more particularly to Figs. 1 to 4 inclusive, in which the hanger is shown arranged above the door, it will be observed that I suspend the door, indicated at 5, from the spaced arms 6 by means of brackets 7 secured to the upper portion of the door, and pivoted at 8 to the lower ends of the arms. The arms 6 are in turn suspended from a parallelogram which consists of the lower bar 9, secured by fastenings 3 extendmg through openings 1, to the wall of the building in which the door opening is formed; the upper bar 10, parallel with the lower bar and spaced from it; and the end bars 11 which are parallel with each other and which are pivotally connected at their opposite ends to the bars 9 and 10 at the points 12 and 13 respectively. The upper ends of the arms 6 are pivotally connected to the upper bar 10 of the parallelogramor wall section as it may be called of the hanger, at the same point 13 on which the end bars 11 are pivoted. Preferably the upper ends of the'bars 11 and arms 6 are offset toward each other, as indicated in the drawings, to provide ample clearance be tween the elements.

Arranged midway between and parallel with the bars 11, is a lever let pivoted at its lower end on the bar 9 at the point 15, and at a point removed from its upper end, to the upper bar 10 at 16. The portion of the lever 14 above the bar 10 is bent or inclined at a proper angle, determined by experiment, toward one of the arms 6, and a link 17 connects the upper inclined portion 18 of the lever with the arm 6 toward which this portion is inclined. The link is pivoted at one end at point 19 to lever 14, and adjacent its other end is provided with a series of openings 20 adapted to be selectively passed over the bolt 21 carried by arm 6 for pivotally connecting the link with said arm. The ratio of the distances be" tween points 13 and 21 and 19 and 16, as determined by experiment, is such that, when the bolt 21 is in the central or neutral one ofthe series of openings 20 the door in being shifted from closed to open position and viceversa, maintains a constant level and traverses a. constant horizontal path, the arms 11 and 6, moving at an equal rate of speed so that the bisector of the varying angle described by either pair of these arms is always perpendicular. This is illustrated in Fig. 1, in which the dotted line position of the parts illustrates the position assumed when the door is in full open position, the full line position being that which is assumed when the door is in half open position. 7

It will be understood, of course, that the hanger is applicable to doors which move either to the right or to the leftin opening, and the principle of action of the parts is exactlyv the same in either case. This action be briefly. described, by way of illustration, with reference to Fig. 1. Here, when thefdoor. moves from, full line to dotted line positlon, the movement of the arm 6 to which the linkis connected, inswinging on itspivot, is imparted by a pull through the link 11 and lever 14 to the bar 10 and arms 11;,swinging the latter over on their pivot 1'2'at af rate of speed equal to the movement of the arms 6. When the door isshifted fromdotte d to full line position, a push is impartiecltlirougli the link and lever to the arms 11, moving them in a reverse direction, and at a rate of speed equal to the movement of arm 6, as will be understood. [When it .is desired that the door return automatically to closed, from open position, thelink 17 is so adjusted with relation to the arm. 6 to which it is connected, that-the bolt 2-1 passes through one of the series of openings occurring on one side or the other of. the central-or neutral opening. In; Fig. 2fthel arrangement is such that the door is moved a)" theleft in being opened, and auto-I maatically returns to closing position, moving toward the right to assume closed position. In this instance the bolt 21 passes through theoutermost of the series of openings 20, and. as the door is shifted toward theleft, thearm 6 will move gradually up.- wax-Ja about their pivots 13, and will thus bodily lift the door as it is swung toward the left in. being opened, so that when the door'is'released from its-open position it will a'iit'oniatically, by action of gravity, swing back 'towarclthe right into. closed position. Vilhn theihanger is applied: to adoor which ismoved to. the right in being opened, and it" is desired to have the door move automati'call"intoclosed dosition: thebolt 21 is.

, y l a.

passed through the innermost one of the series 'of openings, or that one nearest the pivot point 19, so that. when the door is shifted to the right, the arms 6 in, moving toth'e'rig'ht, will move upwardly about their pivots, andthe reby bodily lift thedoor, so that when it is released it will automatically shift into closed. position.

. T'IIi oiider'thatthe hang or may be properly sn'pported and guided in, its movement, I

The arrangement so far described refers particularly to that one in which the hanger is arranged above the door as shown in Figs.

1 to l-incl'usive. vVhemhowever, by reason connecting bar 10 ,jand the lever 14* is. like}.

wise pivoted at 16 to, the bar 1 0 adjacent its lower ofl'set end 18?, the upperend of the lever being pivoted to a bracket which is also? secured tothe wall above the door, the pivot point of the lever and bracket being indicatedat 15. The arms 6: are. pivotally connected at their lower ends withr the bar 10? on the point 13", and at their upper ends are. pivotally, connected as at 8?, see F igz 5 with the door adj acentthe upperedge of the latter. The lever 14? is connectedby the link 17 with one of the armsvtif toward which the. portion 18? of the lever is. inclined The operation of the parts in this instance is identical with; that already. described, and it isthought therefore that a detail d dc;- scription of the. operation would bev supers fluous. Suflice it to say that the position indicated in Fig.6. is thattakenby the parts when the door is in open position, and that, shown, in Fig. 6 is the positionwhen the door; is half closed, It will be. noted that, in this arrangement, the arms ll mayv be vformed of right angular strips of meter if desired, so that whenthe dooris swung into, full open position as-indicatedin Fig. 5, the portions of the arms 11" adjacent the door open ng, willlie in. respectivehorizontzil and vertical lines, so as not to obstruct the corner of the door opening The, arrangement shown in Figs. 5 and: 6 presents many; ad; van; agesin. hanging cardoors ,and' the like.

Although I have described thewpreferred embodiment of. my invention, Ifmay desire to make such changes in, the. COl? i uotion, combination, and arrangement of parts; thereof, as. do. not departfrom the spirit of the in vention and the scope of the}. appended claims. i t i I I claim: 1.
